Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile painting auxiliary tools, and more specifically, to an anti-flow mark device. Background Art
[0002] Electrophoretic flow marks are common process defects in the process of body painting, and are often seen on the hemming of the four doors and two covers of the body. They are also called secondary flow marks or secondary sagging. They refer to the surface being completely normal in the electrophoretic wet film state, but electrophoretic flow marks appear in the gap structure of the body after drying. That is, because there are gaps in the hemming or overlapped parts of the body, the water-based electrophoretic paint has a strong wettability on the cleaned steel plate. When the gap is appropriate, the electrophoretic paint will accumulate in the gap after entering under the action of the liquid surface tension. Even after electrophoresis, it is difficult to completely clean it. When the temperature rises sharply during baking, the liquid surface tension is destroyed or even boils. The tank liquid in the gap flows out on the outer surface of the body fender, forming electrophoretic flow marks in the form of dots or strips.
[0003] Electrophoretic flow marks are formed outside the electrophoretic layer and do not affect the quality of the electrophoretic layer itself, so electrophoretic flow marks dripping on non-external surfaces do not need to be treated. However, for electrophoretic flow marks on the external surfaces of the car body fenders, side panels, etc., the middle coating and topcoat layer cannot effectively cover them, resulting in paint surface defects, which must be eliminated during the production process. In order to prevent the flow marks from affecting the appearance of the paint film, the flow marks must be polished and repaired before the subsequent painting. At present, the method of eliminating electrophoretic flow marks after drying is: polishing with sandpaper, but this method not only increases the working time of painting, but also consumes a lot of manpower and material resources, increases the cost, and when the electrophoretic flow marks are serious, the polishing time exceeds the production cycle, which will cause production line stoppage. In addition, the electrophoretic paint film will inevitably be damaged during polishing, making the electrophoretic paint film thinner or even showing the metal layer after polishing. The anti-corrosion performance of the polished part will be weakened, which will bring hidden dangers to the car body corrosion.
[0004] There are also anti-flow mark devices on the market for avoiding electrophoretic flow marks, but such anti-flow mark devices are prone to loosening and failure in the electrophoretic tank, resulting in the inability to effectively fix the parts, and the flow guidance effect on the electrophoretic paint is not ideal, and the production efficiency is difficult to be effectively improved, affecting the quality of the coating process.
